New clinical research indicates that a widely used food additive, carboxymethylcellulose, alters the intestinal environment of healthy persons, perturbing levels of beneficial bacteria and nutrients. These findings demonstrate the need for further study of the long-term impacts of this food additive on health.

Which diet is better: moderately reduce meat consumption and eat more fruit, vegetables and wholegrain products or eating more fish and seafood? Or even switch completely to a vegan diet? A new study shows that the answer to these questions is not as clear-cut as one might think -- depending on which impacts one closely looks.

A decline in metabolism and endurance of skeletal muscle is commonly observed in obese patients, but the underlying mechanism is not well-understood. A research team uncovers a new mechanism to explain how obesity jeopardizes the functions of skeletal muscle and provides a potential treatment against the disease.
